Rapid movement of the separation point occurred when it passed through the joint section. One of reasons for the occurrence of a highly asymmetrical flow causing large side-load is considered to be that the location of the separation point becomes very sensitive to the flow condition when the separation point passes through the joint section., 資料番号: AA0045948029, レポート番号: NAL SP-57}, pages = {160--165}, publisher = {航空宇宙技術研究所, National Aerospace Laboratory (NAL)}, title = {ロケットエンジンノズル形状と横力の発生について}, volume = {57}, year = {2003} }
